- Cerebral atrophy is a common feature of many of the diseases that affect the brain.Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.Atrophy can be generalized, which means that all of the brain has shrunk; or it can be focal, affecting only a limited area of the brain and resulting in a decrease of the functions that area of the brain controls.erebral atrophy is a common feature of many of the diseases that affect the brain.

- Overview. A brain tumor is a collection of abnormal cells in the brain. Brain tumors can be either malignant (cancerous) or benign (unlikely to spread). However, there is a limited amount of space in the skull. Therefore, any brain tumor—even one that is benign—can interfere with the functions of your brain and body.urgery is a common treatment for primary brain tumors. However, not all tumors can be fully removed. In these cases, a surgeon will attempt to reduce the tumor’s size. The extent of removal will depend on the tumor size and location.
